Radiator fan power

[clipto]

I am looking to get this spal push fan for my radiator and was wondering if it's ok to get one that takes 20amps of power to run. I am also running a mini battery. Should this be ok to run? Or is there curtain amp power of the radiator fan I should run? Would I be able to run 2 20 amp fans on the 1 power wire from the stock fan plug? Or is that to much power for it?

I run two 10in fan on mine but i just run them off a power source that comes on with the key. I have them both run together an no problems for two years.

Way too much power for just 1 wire (each fan harness wire is 14 gauge which is not large enough to handle 20A continuously by itself) - you will melt it, not to mention burning out the relay.

However if you connect both radiator harness wires together (and then both harness grounds) for one fan, and connect both condensor harness wires together (and then both harness grounds) for the other fan you could. But only if you rewire the relays so the 2 radiator ones go on together and the 2 condensor ones go on together (or make them all go on together). That way power will be divided over 2 relays and 2 wires for each fan and will be adequately safe. The rewiring of the relays is a bit tricky so pm me if you want to know how.

The mini battery will also deplete real fast when the engine is stopped but the ECU still keeps the fans on (when engine is too hot). May not be enough power to re-start the car if fans are on more than 15 seconds (just a guess).

bigger wire and better relay

^^^this. Just get you a relay and wire it off the ignition problem solved

Ok I really wanna work something out becuase 1800cfm fans are nice! Thanks.
